Lets check...
42/56 = 56/64
cross multiply
(56)(56) = (42)(64)
3136 = 2688...(incorrect)...these are not proportional
proportions are nothing but equivalent fractions
42/56 = 3/4
56/64 = 7/8
as u can see, they are not equivalent fractions...so they are not proportional
Answer:
7^1/3
Step-by-step explanation:
the answer is 7 to the exponent of 1/3
Explanation;
2x=256
2x=2 exponent 8
x=8
4x-1=64
x-1=4³
x-1=3
x=3+1
x=4
8x-2=16
x-2=8²
x-2=2
x=2+2
x=4
3x-2=81
x-2=3⁴
x-2=4
x=4+2
x=6
3²x=9 exponent 5x-4
2x=5x-4
4=5x-2x
4=3x(<em>divide</em><em> </em><em>bo</em><em>th</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>3</em><em>)</em>
<em>x</em><em>=</em><em>4</em><em>/</em><em>3</em>
