Answer:

4^15

Step-by-step explanation:

Ok, so lets replace the base, 4, with x so we don’t get confused by it:

(X^3)^5

When we raise a power to a power, we multiply them , so:

(X^15)

Remember x is 4, so:

4^15 is the answer

Rewrite the expression as a sum of terms, where each term is in the form k\cdot a^nk⋅a
muminat

Answer:

  2a^{\frac{5}{2}}-4a^{-\frac{1}{2}}

Step-by-step explanation:

It looks like you want to expand the expression ...

  \sqrt{a}\left(2a^2 -\dfrac{4}{a}\right)

Use the distributive property and rules of exponents.

  =2a^{(\frac{1}{2}+2)}-4a^{(\frac{1}{2}-1)}\\\\=\boxed{2a^{\frac{5}{2}}-4a^{-\frac{1}{2}}}

_____

The relevant rules of exponents are ...

  √a = a^(1/2)

  1/a = a^-1

  (a^b)(a^c) = a^(b+c)

fomenos

Answer: 0.1 or 1/10

Step-by-step explanation:

\left(\frac{3}{4}-\frac{2}{3}\right)\cdot \:1\frac{1}{5}

1\frac{1}{5}=\frac{6}{5}

\left(\frac{3}{4}-\frac{2}{3}\right)\cdot \frac{6}{5}

  \frac{3}{4}-\frac{2}{3}    =\frac{9}{12}-\frac{8}{12}

=\frac{1}{12}

\frac{6}{5}\cdot \frac{1}{12}

Cross, cancel common factor

\frac{1}{2}\cdot \frac{1}{5}

=\frac{1}{10}

Tim is thinking of two numbers. The quotient of the two numbers is 9. The difference of the two numbers is 48. The sum of the tw
Paladinen [302]
Let the two numbers be x and y, then
x - y = 48 . . . (1)
x + y = 60 . . . (2)

(1) - (2) => -2y = -12 => y = -12/-2 = 6
From (1), x - 6 = 48 => x = 48 + 6 = 54

Therefore, the two numbers are 54 and 6.
