Question

What’s it simplified

Answer 1

SIMPLIFYING EXPRESSIONS

`\mathbb{ANSWER:}`

`\sf 3.9^(10)`

`\mathbb{SOLUTION:}`

`\sf ((3.9)^(20) )/((3.9) ^(10) )`

`\sf = (3.9)^(20 \: - \: 10)`

`\sf = \boxed{ \sf 3.9^(10)}`

`\sf \approx 814040.61`

Answer 2

39

Explanation:

When you have an expression like
`(a^(b))/(a^(c) )`, you can simplify it to
`a^(b-c)`. This is one of the exponent rules. In our case, a is 3.9, b is 20, and c is 10.

• So,
  `(3.9^(20) )/(3.9^(10) )` =
  `3.9^(20 - 10)` =
  `3.9^(10)`

Any decimal to the power of 10 moves the decimal 1 place to the left.

So:

• 3.9 × 10 = 39

Therefore, the expression can be simplified to 39.
