Answer:

Equation: 7x + 8x = 180

x = 12

∠CBA = 84

∠CFH = 96

Step-by-step explanation:

We can see that ∠CBA = ∠CFE and ∠CBD = ∠CFH.

We know that the sums of two angles on a straight line are going to be equal to 180.

∠CBA = 7x

∠CFH = 8x

To find the value of x, we must do the following:

7x + 8x = 180

15x = 180

15x/15 = 180/15

x = 12

Now we just substitute to find the angle measures:

∠CBA = 7 · 12 = 84

∠ CFH = 8 · 12 = 96

The required answer is $(7^{\frac{1}{3}})^{3} = (7^{\frac{1}{3}*3}) = 7^1=7$ .

<u>what is a power rule for exponents ?</u>

$(a^m)^n=a^{mn}$ is known as the power rule for exponents. Exponent times power is how you raise a number with an exponent to a power.

A number's exponent demonstrates how many times we are multiplying a given number by itself. 3^4, for instance, indicates that we are multiplying 3 by four. 3*3*3*3 is its expanded form. The power of a number is another name for an exponent. It could be an integer, a fraction, a negative integer, or a decimal.

$(7^{\frac{1}{3}})^{3} = (7^{\frac{1}{3}*3}) = 7^1=7$

Here, we have used the rule $(a^m)^n=a^{mn}$
