1) 42x³y²z⁴/6xy²z³
= 42XXXYYZZZZ/6XYYZZZ
CANCEL
= 7X²Z
2) 3X^-2 × Y^-3 × Z/9 × X^-2 × Y^-4
= (3Z/X²Y³)/(9/X²Y⁴)
= 3Z/X²Y³×X²Y⁴/9
= 3ZY/9
= ZY/3
= 42XXXYYZZZZ/6XYYZZZ
CANCEL
= 7X²Z
2) 3X^-2 × Y^-3 × Z/9 × X^-2 × Y^-4
= (3Z/X²Y³)/(9/X²Y⁴)
= 3Z/X²Y³×X²Y⁴/9
= 3ZY/9
= ZY/3
rishu78655p2mu38:
but the answer willbe 7x^2z
SEE MY ANSWER ALSO 7X²Z I ANSWERED BOTH QUESTION
SEE THE ANSWER
sorry i dont see that but the sec answerwill be 1/3yz
BRO MY ANSWER IS RIGHT ANS IS YZ/3
no your answer is not right
3ZX^-2Y^-3Z/9X^-2Y-4. = Z/3Y^-1 = Z/(3/Y¹ ) = Z×Y/3 = ZY/3. SEE THE ANS MY ANS IS RIGHT
BRO USE FORMULA a^-m = 1/a^m
bro iam not getting it
please write in a copy and then send into me pls
