Simplify (5^2 x 7^4)^10

a. 5^20 x 7^40
b. 5^12 x 7^14
c. 5^60 x 7^60
d. 35^60

  A.  5^20 x 7^40

Step-by-step explanation:

The exponent outside applies to each factor inside parentheses. The rules of exponents say ...

  (a^b)^c = a^(b·c)

so, you have ...

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
