Question

calculati b) 9 la puterea 3 - (3 la puterea 5)totul la putearea a 2 + 8 la puterea 4 - (2 la puterea 4)totul la puterea 3

c) 2 la puterea 7 : 4 la puterea 3 + 3 la puterea 3 x 27 : 3 la puterea 5 + (3 la puterea 1 x 2 la puterea 4 - 4 la puterea 2 ) : 2 la puterea 3

Answer 1

9³- (3⁵)²+8⁴-(2⁴)³=(3²)³-3¹⁰+(2³)⁴-2¹²= 3⁶-3¹⁰+2¹²-2¹²= 3⁶-3¹⁰=729-59049=−58320

2⁷÷4³+3³×27 ÷3⁵+(3¹×2⁴-4²)÷2³=2⁷÷(2²)³+3³×3³ ÷3⁵+(3¹×2⁴-2⁴)÷2=
=2⁷÷2⁶+3⁶ ÷3⁵+2⁴(3-1)÷2=2+3+2⁵=5+32=37
