Answer:

The answer is

<h2>6√a</h2>

Step-by-step explanation:

√16a - √49a + √81a

Simplify the surds

That's

(√16)(√a) - (√49)(√a) + (√81)(√a)

4√a - 7√a + 9√a

= 4√a + 2√a

<h3>= 6√a</h3>

Can you guys please help me!!!

Answer:

x=6

Step-by-step explanation:

When we multiply exponents with the same base we add the exponents

When we divide exponents with the same base we subtract the exponents

4^3 * 4^3 ÷4^3 *4^3

We will work from left to right

Multiply means add

4^(3+3) ÷4^3 *4^3

4^6÷4^3 *4^3

Now divide means subtract

4^6÷4^3*4^3

4^(6-3)*4^3

4^3 *4^3

4^3*4^3

Multiply means add

4^(3+3)

4^6

4^6 = 4^x

The bases are the same so the exponents must be the same

x=6
