2,9ab10×(-8)abz-6,04mt×6m4t = -23,2a²b²z-144,96m²t²
3,4a+n+n-23,01a = -19,61a+2n

a) 19z-8tz-3zt = 19z-11zt
б) 2x+8x²-3+2x×2x = 2x+8x²-3+4x² = 2x-3+12x²
в) 5pk+2p²+(3p×4k)-(-p²) = 5pk+2p²+12pk+p² = 17pk+3p²

а) -1,79х+95xy²+46xy² = - 1,79x +141xy² = x(-1,79+141y²) = 3(-1,79+1,41) = -1,14
б) то же самое.
