1. 12.12.-0.253.6/134.-3/85.*square root* of 15I just need a little help. Thanks for any feedback:)
additive inverse : just take the negative. So, for1.", the additive inverse = -12.1 multiplicative inverse: just take the reciprocal. So, for3.", the multiplicative inverse = 13/6
The additive inverse is what, when added to the original number, gives you 0. The multiplicative inverse is what, when multiplied by the original number, gives you 1. 1. 12.1 The additive inverse is -12.1. The multiplicative inverse is 1/12.1, or 10/121. 2. -0.25 The additive inverse is 0.25. The multiplicative inverse is 1/-0.25, or 1/-(1/4), or -4. 3. 6/13. The additive inverse is -6/13. The multiplicative inverse is 1/(6/13), or 13/6. 4. -3/8. The additive inverse is 3/8. The multiplicative inverse is 1/(-3/8), or -8/3. 5. sqrt(15) The additive inverse is -sqrt(15). The multiplicative inverse is 1/sqrt(15). You can simplify this by multiplying it by sqrt(15)/sqrt(15). The result is sqrt(15)/15. Done.
