Simplify the exponential problem 7b^5/b^4

Norma-Jean [14]

Solution:

If the numerator and the denominator have like bases in exponents, then the exponents subtract.

$\frac{7b^5}{b^4} = 7b^5^{-4}$
=> $7b$

Thus, 7b is the simplified expression.

Find X if m/_ UVH=50°, m/_HVW=25x-5, and m/_ UVW = 35x-5.

ra1l [238]

Step-by-step explanation:

first you have to solve for x

35x - 5=50

35-35x-5= 50-35

x-5=15

x- 5÷5=15÷5

x=3

Now we have to substitute x into the equation.

35×(3)-5=

175-5=170

angle UVW= 170

to find angle HUW instead of solving the equation just subtract 170 from 50 and you will get 120.

angle UVH=50

angle HUW=120

angle UVW=170

I hope this helps srry it took so long but gn and gl.

What's is the square root of 63

QveST [7]

You want to be finding out what two factors (where one of them is a perfect square) has the produce of 63. It seems like 9 x 7 (9 is the perfect square) works.

$\sqrt{63} = \sqrt{9 \times 7} = \sqrt{9} \times \sqrt{7}$

The square root of 9 is 3 so we can just have $3 \sqrt{7}$ (which just means 3 times the square root of 7).
