Question

[(1/4)^-3 divide sign (1/4)^2]^-2

I got (1/4)^10 but I got it wrong

(3^1/2)^3
_______ I got 1/216
9

(-56r^2)divide sign (-7r^2)= I got 8r

x(y)(x)(2y)

(12) (10xy^3) (3x^2y^2) (5x) (2y)

simplify sqaure root of 160000
simplify sqaure root of 0.04
simplify 3 * square root 81
simplify square root of 900
simplify square root of 0.0025simplify [(a^2bc^4)(ab^3c^2)]^2
___________________
(b^2c^5)^3
what is 4^-5/2 expressed as a radical with positive exponents

Thank you so much

Answer 1

((1/4)^-3/(1/4)^2)^-2 =
((1/4)^-5)^-2 = (1/4)^10 = 9.54*10^-7

(3^1/2)^3 = 3^(3/2) = 5.196.

-56r^2/-7r^2 = 8.

x*y*x*2y = 2X^2Y^2

3600X^4Y^6.

sqrt(16*10^4) = 4*10^2 = 400.
sqrt means Square root.

sqrt(0.04) = sqrt(4*10^-2) = 2*10^-1 =
0.20

3*sqrt(81) = 3*9 = 27

sqrt(900) = sqrt(9*10^2) = 3*10 = 30

sqrt(0.0025) = sqrt(25*10^-4) = 5*10^-2=
0.05

4^(-5/2) = 4^(-1/2)^)5 = 1/(4^(1/2)5 =
1/sqrt(4)^5

Answer 2

I can not remember the rules and how to do the problems
