How to put these in a simply form?
(-2)* (-2)* 10 *10 *10 *10.
21*21*21+(-1)(-1)(-1)(-1).

370,4440,001

Step-by-step explanation:

(-2) • (-2) • (10) • (10) • (10) • (10) = 40,000

21 • 21 • 21 = 9261

(-1) • (-1) • (-1) • (-1) = 1

(40,000) (9261) + 1

(370,440,000) + 1 = 370,4440,001

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
