How do you do it this question?

Should be A.

SOLUTION:

Well we can just simplify the exponents for all of them:

A. (3/5)^3, simplify it becomes:

3^3 / 5^3 = 27/125

B. 3 / 5^3.

This becomes 3 / 125.

C. (3/4)^2.

Simplified: 3^2 / 4^2 = 9 / 16.

D. 3^3 / 5^5 = 27/ 3125.

u bout ugly as   a mf

step-by-step explanation: lol

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
