(A)7²-4=

(B)2³+10=
(C)4²+7⁰=
(D)5⁰+5³=
(E)2³+2⁴=
(F)80¹+1⁸⁰=
(G)5²-3²=
(H)1⁸⁰+0⁷⁰

Answer 1

a) 7² - 4 = 49 - 4 = 45

b) 2³ + 10 = 8 + 10 = 18

c) 5² - 6 = 25 - 6 = 19

d) 4² + 7⁰= 16 + 1 = 17

e) 5⁰+ 5³= 1 + 125 = 126

f) 2³+ 2⁴ = 8 + 16 = 24

g) 10³ - 10² = 1000 - 100 = 900

h) 80¹ + 1⁸⁰ = 80 + 1 = 81

i) 5² - 3² = 25 - 9 = 16
