a) (3)2/9
b) (3)-1/9
c) 9
d) 3
Answer: d
Explanation: According to laws of exponents, am an = a(m+n)
Applying that rule here, (3)1/3 * (3)2/3 = 3(1/3+2/3)
= 3(1+2)/3
= 33/3
= 31 = 3. - By simplifying (7)2/5 * (7)3/4, we get __________
a) (7)6/20
b) 7
c) (7)23/20
d) (7)-7/20
Answer: c
Explanation: According to laws of exponents, am an = a(m+n)
Applying that rule here, (7)2/5 * (7)3/4 = (7)(2/5+3/4)
= (7)((2*4)+(5*3))/(5*4)
= (7)(8+15)/20
= (7)23/20.

a) 81
b) 9
c) 3
d) 27
Answer: a
Explanation: According to laws of exponents, am an = a(m+n)
Applying that rule here, (9)1/4 * (9)7/4 = (9)(1+7)/4
= (9)8/4
= (9)2
= 81. - By simplifying (5)3/4/(5)1/4, we get __________
a) (5)1/4
b) (5)3/16
c) 5–√3
d) 5–√2
Answer: d
Explanation: According to laws of exponents, am/an = am-n
Applying that rule here, (5)3/4/(5)1/4 = (5)(3/4-1/4)
= (5)(3-1)/4
= (5)2/4
= (5)1/2
= 5–√2. - By simplifying (4)9/(4)3, we get __________
a) 427
b) 46
c) 412
d) 43
Answer: b
Explanation: According to laws of exponents, am/an = am-n
Applying that rule here, (4)9/(4)3 = 4(9-3)
= 46.
