Question

Answer 1

\(i,80-\left(4.5^2-3.2^3\right)=80-\left(4.25-3.8\right)=80-\left(100-24\right)=80-76=4\)

 

\(k,2^2.3-\left(1^{2000}+8\right):3^2=4.3-\left(1+8\right):9=12-9:9=12-1=11\)

 

\(o,\left(3^4-2.4^2\right).\left(5^2-2^4\right)+6=\left(81-2.16\right).\left(25-16\right)+6=\left(81-32\right).9+6=49.9+6=441+6=447\)

 

\(q,\left(100-97\right)^2+7^7:7^6+2012^0=3^2+7+1=9+7+1=17\)

 

 

Answer 2

i; \(=80-\left(4\cdot25-3\cdot8\right)\)

\(=80-100+24=4\)

k: \(=4\cdot3-1=11\)

o: \(=\left(81-2\cdot16\right)\cdot\left(25-16\right)+6\)

\(=49\cdot9+6=447\)

Answer 3

i) = 83,75

k) = 11

o) = 19606

q) = 59
