Simplify (3a^3 b^3)(4ab^2)^2

mamaluj [8]

$\bf (3a^3b^3)(4ab^2)^2\implies (3a^3b^3)(4^2a^2b^{2\cdot 2})\implies (3a^3b^3)(4^2a^2b^4)
\\\\\\
3a^3b^34^2a^2b^4\implies 3\cdot 4^2a^3a^2b^3b^4\implies 3\cdot 16a^{3+2}b^{3+4}\implies 48a^5b^7$

Eleven more than four times a number equal the number less 7 find the number

bixtya [17]

For this case we have to:

x: Let the variable representing the unknown number

We algebraically rewrite the given expression:

Eleven more than four times a number, is represented as:

$11 + 4x$

The number less 7, is represented as:

$x-7$

Thus, the complete expression is:

$11 + 4x = x-7$

We subtract x from both sides of the equation:

$11 + 4x-x = -7\\11 + 3x = -7$

We subtract 11 from both sides of the equation:

$3x = -7-11$

Equal signs are added and the same sign is placed:

$3x = -18$

We divide by 3 on both sides of the equation:

$x = - \frac {18} {3}\\x = -6$

Answer:

$x = -6$
