Answer 1

Answer:

1. (a^2)×(2a^22)×(4a^26)

4a×2a×a^2+22+26

8a^50.

2. (2/3xy)×(-9/10 x^2 y^2)

$\frac{2}{3} \times \frac{ - 9}{10} \: \: xy \times x {}^{2} y {}^{2}$

3 cuts -9 = -3

2 cuts 10= 5

xy sum x2y2 = x3y3

so got

$\frac{ - 3}{5} x {}^{3} y {}^{3}$

$3. \: (- \frac{10}{3}pq {}^{3}) \times ( \frac{6}{5} p {}^{3}q)$

$\frac{ - 10}{3} \times \frac{6}{5} \: \: pq {}^{ 3} \times p {}^{3}q$

3 cuts 6 = 2

5 cuts -10 = -2

pq3×p3q = p4q4

so got

$- 4p {}^{4}q {}^{4}$

$4. \: \: x \times x {}^{2} \times x {}^{3} \times x {}^{4}$

$x \times x \times x \times x \times {}^{1 + 2 + 3 + 4}$

so got

$x {}^{10}$
