Answer:

$d)\ \frac{81}{m^{7}}$

Step-by-step explanation:

$(3m^-4)^3(3m^5)$

First, simplify $(3m^{-4})^3$ :

$(3m^{-4})^3\\\\3^3*m^{-4*3}\\\\27m^{-12}$

$27m^{-12}*3m^5\\\\27*3 *m^{-12+5}\\\\81m^{-7}\\\\81*\frac{1}{m^{7}} \\\\\frac{81}{m^{7}}$

Question in attachment

denis-greek [22]

Answer:

(a) x + y = 63 OR 3x = 63

(b) 21

Step-by-step explanation:

Let Vijay's age be x and Ajay's be y.

Ajay is twice as old as Vijay

==> Ajay's age = 2 × Vijay's age

==> y = 2x

Sum of their ages = 63

==> x + y = 63

Substituting 2x for y:

==> x + 2x = 63

==> 3x = 63

Solving the above-obtained equation:

==> x = 21

Ajay's age = 2 times that of Vijay

==> y = 2x

==> y = 2×21

==> y = 42
