Question 79

Simplify $$(b^{2}x^{3}a^{2}z^{4})\times (b^{2}x^{4}a^{4}z^{3}/(a^{3}b^{2}z^{4})$$

Solution

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

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

= $$(b^4x^7a^6z^7)\div(a^3b^2z^4)$$

= $$(b)^{4-2}(x)^{7}(a)^{6-3}(z)^{7-4}$$

= $$b^2x^7a^3z^3$$

=> Ans - (A)
