Answer:

  1/108

Step-by-step explanation:

Make use of the rule of exponents ...

  a^-b = 1/a^b

__

  \dfrac{2^{-2}}{3^3}=\dfrac{1}{(2^2)(3^3)}=\dfrac{1}{4\cdot 27}=\boxed{\dfrac{1}{108}}

__

If you type this expression into your calculator, you will get the repeating decimal ...

  \dfrac{2^{-2}}{3^3}=0.00\overline{925}=\dfrac{925}{99900}=\boxed{\dfrac{1}{108}}

Some calculators will convert this to a fraction for you.

One day, he bought 10 pairs of socks for $2.50 each and 3 pairs of shoes for dollars each. He
IrinaVladis [17]

Answer:

2.50(10) + 3x = 135.97, x = 38.66

Step-by-step explanation:

This should be pretty simple.

Basically, we know that he bought 10 pairs for 2.50 so that's $25 right there.

Our total is 135.97 though-

so here, we take our total from the right side of the equation, and subtract 25 from that.

135.97 - 25 = 115.97

Since he bought three pairs, divide it by 3.

115.97 / 3 = 38.66

One pair of shoes costs $38.66 - hope this helps!

A decimal that is like .11 the amount of #s in the decimal is 2 so it'll mean 2 0s like that would be 11/100. So if it was .209 it would be 209/1000.

Describe how (2^3)(2^-4) can be simplified
Naddika [18.5K]

Answer:

Add the exponents and keep the bases the same. Then find the reciprocal and change the sign of the exponent

Step-by-step explanation:

When multiplying exponents with the same base number, you can add the powers. (If it was dividing, you would subtract the powers). You would then get 2^{-1}.

  • 2³ = 8,
  • 2² = 4,
  • 2^1 = 2,
  • 2^0 = 1

The pattern is to divide by 2. This means that 2^{-1} would be 1 ÷ 2 which is 1/2.

Tip: Any number to the power of -1 means to give its reciprocal.

Hope this helps!
