Answer:
Step-by-step explanation:
Starting point:
1) Factor it by Prime Factor Method 72 and 50
2) Plug it in the factored form. Every exponent to the second power will be outside the radical, so its roots.
3) Rationalize it multiplying by the radical, so that you can eliminate the square root on the denominator.
7
We certainly already know that 49 = 7².
To be able to answer this question, let us use one of the following exponent properties.
Thus 49 to the power of ¹/₂ equals 7.
- - - - - - -
Now we relate rational exponents with the root form.
In general,
Especially for will be
Based on the above properties, 49 to the power ¹/₂ can be written as,
We state it as 'the square root of 49'.
Thus the result is
Another example:
What's 100 to the power of ¹/₂ ? The answer is
Keywords: 49 to the power of ¹/₂, 7, the exponent properties, the root form, the square root of 49, the power, rational exponents
By the use of exponent properties we get, 7 is 49 to the power of 1/2.
Let us use one of the following exponent properties.
(xᵃ)ᵇ = xᵃᵇ
=
2 * 1/2 = 2/2
= 1
7¹ = 7.
Therefore, 49 to the power of 1/2 is equal to 7.
