7.003 x 10 to the power of 4

Answers

In scientific notation, just move the decimal point over however many numbers are in the power. 

In 7.003 • 10^4, move the decimal point over 4 places to the right, (or left if it's negative) making it 70,030
Here you need to follow the order of operations.
Parenthesis
Exponents
Multiply
Divide
Add
Subtract
So, following these steps the first thing you would do is multiply 10 to the power of 4 (10^4).
10^4 = 10,000
Next, you would just multiply 7.003 * 10,000 
7.003 * 10,000 = 70,030

No it's not. If you raise any decimal number less than one to a power of 2, the number just gets smaller. 

Hope this helps & makes sense ! (:
Any positive decimal less than 1 will get a value less than the original

The solution is Option A.

The value of x in the equation 4x - 5 = -6x + 15  is x = 2

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be = A

Now , the value of equation A is

4x - 5 = -6x + 15   be equation (1)

Now , on simplifying the equation , we get

4x - 5 = -6x + 15

Adding 6x on both sides of the equation ,we get

10x - 5 = 15

Adding 5 on both sides of the equation , we get

10x = 20

Divide by 2 on both sides of the equation, we get

x = 20/10

x = 2

Therefore , the value of x is 2

Hence , The value of x in the equation 4x - 5 = -6x + 15  is x = 2
