1) x^2 + 7
a) x=1
x^2 + 7 = 1^2 + 7=1+7=8
б) x=10
x^2 + 7 = 10^2 + 7=100+7=107
2) 2m^2 - 9
a) m = 8
2m^2 - 9 = 2*8^2 - 9 = 2*64-9=128-9=119
б) m = 100
2m^2 - 9 = 2*100^2 - 9 = 2*10000-9=20000-9=19991

1) 2^5 + 5^3 = 2*2*2*2*2 + 5*5*5 = 32 + 125 = 157
2) 6^3 - 6^2 = 6*6*6 - 6*6=216-36=180
3) 4^3 / 8^2 + 2^3 = 4*4*4 / 8*8 + 2*2*2= 64 / 64 +8 = 1 + 8= 9
4) (51-47)^3 * 10^3 = 4^3 * 10^3 = 4*4*4 * 10*10*10 = 64 * 1000 = 64000
