Answer:

Hi there!

Your answers are:

1) 38^10

2) 20^3

Step-by-step explanation:

1) Theres a property that goes like this:

(x^m)^n = x^mn

When you do a power of a power, you multiply them together!

2) There's a property that looks like this:

x^ m / x^n = x^ m-n

When dividing exponents, subtract!

Hope this helps!

Solve for x<br> a 2.2<br> b 5.4<br> c 6.5<br> d 7.2
Reika [66]

Answer:

D

Step-by-step explanation:

Given that the segment is an angle bisector then the ratio of sides and base are equal, that is

\frac{10}{4} = \frac{18}{x} ( cross- multiply )

10x = 72 ( divide both sides by 10 )

x = 7.2 → D
