Question 29

Simplify $$(b^{5}x^{2}a^{3}z^{4})*(b^{3}x^{2}a^{4}z^{5}) / (a^{2}b^{3}z^{2})$$

Solution

Expression : $$(b^{5}x^{2}a^{3}z^{4})*(b^{3}x^{2}a^{4}z^{5}) / (a^{2}b^{3}z^{2})$$

= $$(a)^{3+4}(b)^{5+3}(x)^{2+2}(z)^{4+5} \div a^2b^3z^2$$

= $$a^7b^8x^4z^9 \div a^2b^3z^2$$

= $$(a)^{7-2}(b)^{8-3}(x)^4(z)^{9-2}$$

= $$a^5b^5x^4z^7$$

=> Ans - (B)
