I believe it's 8.25 x 10-6
in scientific notation, we simply leave an number to the left of the decimal dot, so in 0.00000825, we need to move over the dot to 0000008.25 , and for that, we have to move it 6 slots to the right, meaning an exponent of -6, namely 10⁻⁶.
Step-by-step explanation:
x² - 2 = 2^(2/3) + 2^(-2/3)
x² = 2^(2/3) + 2 + 2^(-2/3)
x² = (2^(1/3))² + 2 × 2^(1/3) × 2^(-1/3) +
(2^(-1/3))² (It is in the form of a²+2ab+b²)
x² = (2^(1/3) + 2^(-1/3))²
x = 2^(1/3) + 2^(-1/3)
calculate the depth of the tank
210 pounds
First, we are going to find the exchange rate from dollars to pounds.
We know form our problem that 800 dollars are 560 pounds. so:
pounds per dollar.
Next, we are going to multiply our exchange rate by the number of dollars we want to change, 300:
We will get 210 pounds for 300 dollars
Answer:
210
