Question

已知2的x次方=3,2的y次方=5,求2的3x+2y+2 次方的值

求正确率。

Answer 1

=2的(3x)次方乘以2的(2y)次方乘以2的2次方
=[2的x次方]³乘以[2的y次方]²乘以2²
=3³×5²×2²
=2700

Answer 2

2^x=3,x^y=5
2^(3x+2y+2)
=2^3x×2^2y×2²
=(2^x)³×(2^y)²×2²
=3³×5²×2²
=27×25×4
=2700

Answer 3

2的3x+2y+2 次方
=(2的X次方)的三次方*[（2的y次方）的平方][2的2 次方]
=27*25*4

=2700

Answer 4

2^x=3,2^y=5
2^(3x+2y+2)=2^3x * 2^2y * 2^2=3^3 * 5^2 * 4=2700
