1.x=2+1+4+6+8+......+100-50,x=p.p,√x?

2.x=6+12+18+.......+228
3. a)√(-2)⁴•(-14)²•(-15)²
b)√(-3)⁴•7²•(-2)²


plss repede​

Answer 1

x=2+1+4+6+8+......+100-50

x=1+2(1+2+3+4+...+50)-50

x=1+2×50×51:2-50

x=1+2550-50=2501

x=6+12+18+.......+228

x=6(1+2+3+...+114)

x=6×114×115:2

x=39330

√(-2)⁴•(-14)²•(-15)²=4×14×15=840

√(-3)⁴•7²•(-2)²=9×7×2=126
