Answer 1

resultado:

a)-(0.3)+√0.81+0.2²+2.1=3.34.

b)-4.74.

Explicación paso a paso:

a)-(0.3)+√0.81+0.2²+2.1

=0.3+√0.81+0.2²+21

0.2²+2.4+√0.81

0.04+2.4+√0.81

0.04+2.4+0.9

=3.34

b)-3√0.16(0.2)+4.5

=3√0.16x0.2+4.5

=0.6√0.16+45

=0.24+45

=4.74

c)-0.5²+√36+(0.02)-0.15

9

=0.5²+√36+0.02-0.15

9

=0.5²+2+0.02-0.15

=0.5²+1.87

=0.25+1.87

=2.12
