30 - 4(2+5) = 2 This makes: 30 - 4(7) = 2 30 - 28 = 2
The value of 4 to the power of -2 is 0.0625
Uh, what digit? Here are the values for all of them. The 4's value is 400. The 3's value is 30. The 2's value is 2. The 6's value is 6 tenths. The 7's value is 7 hundredths.
trun it into sin( 45 + 30 ). sin ( 45 + 30 ) = sin30cos45 + cos30sin45 sin30cos45 + cos30sin45 = (1/2)((sqrroot2)/2) + ((sqrroot3)/2)((sqrroot2)/2) (1/2)((sqrroot2)/2) +((sqrroot3)/2)((sqrroot2)/2)=((sqrroot2)/4) + ((sqrroot6)/4) ((sqrroot2)/4) + ((sqrroot6)/4)= ((sqrroot2) + (sqrroot6)) /4
