Question

Simplify this can someone help please

Answer 1

We can simplify this in one of two ways:

1.

We multiply 81 * 81 * 81 * 3 * 3 * 3 * 3, and then figure out what factor of 3 that is.

2.

Or, the easier way, is to figure out what factor of 3 81 is and go from there.

Let's multiply by 3 until we get 81:

3 * 3 = 9

9 * 3 = 27

27 * 3 = 81

We've multiplied four 3's, so 81 is the same thing as writing 3^4, and we can simplify from there.

*remember! When multiplying exponents, you add them together. When putting an exponent to another exponent, we multiply

$81^3*3^4\\(3^4)^3*3^4\\3^{4*3}*3^4\\3^{12}*3^4\\3^{12+4}\\3^{16}$

3^16 is our answer

Answer 2

Answer:

243 × 12

Step-by-step explanation:

multiply 81 by 3

next multiply 3 by 4

then you got your answer
