Answer 1

a)

${(6 \times 2 \div 3)}^{2}$

=

${4}^{2}$

=16

b)(15×1×2-15)×4-10=15×4-10=50

c)125-9+49+121=286

d)64-25+1-14=26

e) (4÷4+7*9÷7*8)÷4= 8÷4=2

f)

$({2}^{30} + {3}^{28} - 1) \div ({3}^{28} + {2}^{30} - 1) = 1$

g) 2×1+9×1=2+9=11

h)

$( {2}^{14} \times {3}^{10}) \div ( {2}^{13} \times {3}^{9}) + 1 + 1$

$(2 \times 3) + 2 = 8$

i) {[18+5×(4+18)]÷8+9}÷25

=[(18+5×22)÷8+9]÷25

=(128÷8+9)÷25

=25÷25

=1

j) 24+49+1+(64-63)*2012

=24+49+1+1

=75

k) 36+2+9=47

l)

$({3}^{54} \div {3}^{46}) ^{3} \div {9}^{27}$

${3}^{24} \div {3}^{27 \times 3}$

${3}^{24} \div {3}^{81}$

${3}^{ - 57}$
