Equate the powers of the base 112 directly: 0.17├Чz=0.94├Ч6. Simplify to z=0.175.64тАЛтЙИ33.176.
Students often try to calculate the value of 112 raised to the powers instead of comparing the exponents directly using the law of exponents.
Express variables in terms of base 112
Given x=1120.17 and y=1120.94.
x=1120.17,y=1120.94
Substitute into the equation
Substitute x and y into xz=y6: (1120.17)z=(1120.94)6.
1120.17├Чz=1120.94├Ч6
Equate the exponents
Since the bases are identical, set the exponents equal: 0.17├Чz=5.64.
z=0.175.64тАЛ
Final calculation
Divide 5.64 by 0.17 to get zтЙИ33.1764, which rounds to 33.18.
zтЙИ33.18
C is correct because solving the exponential equation 0.17z=5.64 yields zтЙИ33.18.
This exponent comparison method is widely used in Logarithm problems and compound interest calculations where bases remain constant.
